Paraffin cracking by Brønsted acid sites (BAS) in faujasite zeolites is strongly influenced by the presence of nearby extraframework aluminum (AlEF) species (see picture). Although enhanced acidity of faujasites with decreasing framework Al density is directly evident from COads FTIR spectroscopy, H/D exchange reactions, and paraffin cracking activities, such correlations are less evident for AlEF modified zeolites, which is also discussed in terms of structure.
